I agree, and we could do it ourselves with ResetCPUUsage(), but this addon removes the function!

I always want to reset the CPU usage before testing. I don't want login-related CPU tasks contributing to the statistics; Warmup is a much better way of measuring login-related performance. It's very different from runtime performance, and I don't want the two jumbled together into a single statistic. Also, often I want to run multiple tests without /reloading between them.

Currently the only way to reset the cpu results is to edit the addon's .lua file and expose the function it tries to take away from us.

A lot of addon authors report that the API this addon is based on is unreliable (when I report to them their addon was reported too high), however it must be at least partially reliable since I saw tangible results: e.g. Recount gave noticeable FPS increases when it was replaced by tinyDPS based on info from this Addon, or I identified that dynamically created groups in aura addons have extremely high CPU usage compared to static groups and one can not see it only as a number on BrokerCPU but also on tangible FPS increases.
